OK, I think I've seen this before, your disconnecting from the broker, try it again with logging on,
client.logging(true);
from mqtt_client.
Bit more on this, I've fixed the exception, it actually means the broker has not accepted the connection request for on of the following
if (ackMsg.variableHeader.returnCode ==
MqttConnectReturnCode.brokerUnavailable ||
ackMsg.variableHeader.returnCode ==
MqttConnectReturnCode.identifierRejected ||
ackMsg.variableHeader.returnCode ==
MqttConnectReturnCode.unacceptedProtocolVersion ||
ackMsg.variableHeader.returnCode ==
MqttConnectReturnCode.notAuthorized ||
ackMsg.variableHeader.returnCode ==
MqttConnectReturnCode.badUsernameOrPassword) {
or the incoming ack message cannot be decoded at all.

Thank you, I will try the new version soon...

Republished version 1.9.1

Maybe the names should be changed?
error: The name 'ConnectionState' is defined in the libraries 'async.dart' and 'mqtt_client.dart'. (ambiguous_import at [mqtt_test2] lib\main.dart:81)
error: The name 'ChangeNotifier' is defined in the libraries 'change_notifier.dart' and 'change_notifier.dart'. (ambiguous_import at [mqtt_test2] lib\main.dart:93)
error: The name 'ChangeNotifier' is defined in the libraries 'change_notifier.dart' and 'change_notifier.dart'. (ambiguous_import at [mqtt_test2] lib\main.dart:101)
One ChangeNotifier is in the flutter
package, and the other is in observable-0.22.1+3
, both of which are dart packages.

Flutter doesn't really play nice with this. It looses connection to my test device. It could be my fault but idk.

Try prefixing your import of the mqtt_client,
import 'package:mqtt_client/mqtt_client.dart' as mqtt;
then anywhere where you use ant of it prefix it with 'mqtt.' this should stop name clashes. You can do this with any packages.

Yes, I never used flutter but this looks wrong, 'uri = http://127.0.0.1:8106/', mqtt_client just connects to its broker over a socket as shown in the example e.g test.mosquito.org on port 1883(default), there's no HTTP involved, also its logging as 127.0.0.1 which is localhost.
I'm sure there are other flutter users that are using the client, maybe ask on flutter list.
from mqtt_client.
I'm not really sure what the problem is here, but I got it all working with this fork and the example (located in readme.md).

If you want to dig further I'd be happy to help although my experience with flutter and dart is pretty minimal. Otherwise you can close this issue.
